“…This make it is one of the most popular liquid biofuels. New and efficient technologies for ethanol production have begun to emerge, the most common of these technologies are the fermentation method of agricultural waste, fruit waste, and municipal and industrial waste (Khoshkho et al, 2022). Recently, many studies have been reported that the use of bioethanol in diesel engine is better solution to decrease the pollution emissions produced from the combustion of conventional fuel.…”

Recently, most of the researchers focused on provide lower greenhouse gas emissions that emitted from diesel engines by using renewable fuels to be good alternative to the conventional diesel fuel. Ethanol can be derived from renewable sources such as sugar cane, corn, timber and dates. In the current study, the ethanol fuel used in the tests was derived from the dates. The effects of using exhaust gas recirculation (EGR) diesel-ethanol blend (E10) with on engine performance and emissions characteristics have been studied in diesel engine under various engine loads. This study focused the use of oxygen in the bio-ethanol composition to compensate for the decrease occurred by the addition of EGR, which improves the engine performance and reduces its emissions. In this experiment, the ratios of EGR were 10%, 20% and 30% as well as 10% ratio of ethanol was blended into the diesel fuel blend under fixed engine speed. A traditional (without additional systems to reduce emissions) four cylinders direct injection (DI) diesel engine was used for all tests. The brake specific fuel consumption (BSFC) increased with increasing the EGR ratio by 10%, 20% and 30% by 18.7%, 22.4% and 37.4%, respectively. The thermal efficiency decreased under variable conditions of engine load for different ethanol blends. Furthermore, the emissions of NOX decreased when fuelled B10 into the engine in comparison with diesel under low engine load. Significant reduction in the NOx emissions were found when applied EGR in the tests than to the absence EGR for E10 blend and diesel. The NOx reduction rate was 12.3%, 30.6% and 43.4% when EGR rate was 10%, 20% and 30%, respectively. In addition, the concentrations of HC and CO emissions decreased more by 8.23% and 6.4%, respectively, when using E10 in comparison with the diesel for various engine loads. It is indicated that the oxygen reduction by EGR effect was compensated from ethanol blend combustion. The results showed that the combination use of E10 and EGR leads to significant reduction in engine emissions accompanied with partial reduction in the engine performance.

Alternatives to conventional fuel sources have to be found because of the depletion of fossil fuels and stringent regulatory regulations. Every day, the growing population and improved transportation increase the energy demand. Agriculture and food waste management, as well as pollution, remain major issues that require attention. Bioethanol is an effective substitute for gasoline and SI engine diesel. Worldwide, passenger cars typically blend 10 % bioethanol with gasoline. Some nations, like India, have stated plans to blend 20% bioethanol with gasoline starting shortly. This paper describes the process of extracting ethanol from leftover Jatropha deoiled cake (JDC) and various blends' effects on spark-ignited engines' performance. From leftover JDC, bioethanol was produced utilizing the fermentation and vacuum distillation methods. Four different blends were prepared on a volumetric basis at different engine speeds at a constant compression ratio of 10:1 and the wide-open throttle was tested for various performance and emissions. Bioethanol enrichment increased indicated power, volumetric efficiency, and mechanical efficiency. Bioethanol enrichments reduce HC, CO, and CO2 emissions but increase nitrogen oxide emissions. JDCE 15 was found to have the best engine performance out of all the fuel blends tested. This study suggests that, if NOx emission reduction measures are carried out, JDC can be used as a source for the manufacturing of second-generation bioethanol. This research work is eco-friendly solution for bioethanol production.

“…A study revealed that hydrolysis using a sulfuric acid of 2.5% could convert cellulose into reducing sugars up to the concentration of 12 g L -1 [16], with an enzyme catalyst from microorganisms Trichoderma reesei and Aspergillus niger capable of converting corncobs into glucose up to 128.20 mg mL -1 [17]. Bioethanol fermentation typically uses S. cerevisiae yeast [18]. The reduced sugar obtained from the hydrolysis will be converted into bioethanol and carbon dioxide gas.…”

The need for fossil energy is increasing over time and is not proportional to its availability which continues to decline. The consumption of fossil fuels in Indonesia is one of the highest in the world, reaching 75 billion liters in 2019. One of the alternative fuels that can substitute for fossil fuels is bioethanol. The potential utilization of agricultural waste in the form of breadfruit peel (Artocarpus altilis) into bioethanol is studied in Indonesia in this paper. Breadfruit peels contain a concentration of monosaccharides in the form of starch up to 39.5%. In addition, breadfruit production in Indonesia is also relatively high, up to 190,551 tons in 2020. Processing starch into bioethanol requires several stages of processing first. Pre-treatment with enzyme catalysts resulted in higher concentrations of reducing sugars than chemical catalysts. This was followed by fermentation with yeast Saccharomyces cerevisiae to convert reducing sugars into bioethanol. In the final stage, the purification process is carried out by a multilevel distillation process and adsorption to obtain a 99.9% bioethanol purity. It is hoped that this review can help the strategy of processing breadfruit peel waste into bioethanol with an efficient process.
